After stumbling in the film world for some years, director M. Night Shyamalan (The Sixth Sense, Unbreakable, Signs) made a decent comeback with the suspenseful thriller The Visit last year. Now he’s back behind the camera again for another unsettling thriller called Split starring James McAvoy (X-Men: Apocalypse), and the trailer has just debuted online.

Split starts off like your average kidnapping thriller with James McAvoy abducting three young girls and taking them to a dark basement. But the kidnapping is just the beginning of the creepiness that ensues as they learn that this man has some serious mental problems that make their imprisonment that much more horrifying. Watch the Split trailer after the jump.

If anything, this looks like it will have an incredible performance by James McAvoy as he brings 23 different personalities to life, some of which the girls may be able to convince help them escape. The Witch star Anya Taylor-Joy also stars in the film as the lead abducted girl. She’s quite a name for herself in the horror and thriller genre, as she also stars in the sci-fi thriller Morgan coming later this year. The rest of the cast includes Betty Buckley, Jessica Sula, and Haley Lu Richardson,

Thrillers that use the plot device of multiple personality disorder can be interesting, but more often than not they feature a plot twist that you can see coming a mile away. Since this is Shyamalan we’re talking about, I hope the twist doesn’t have anything to do with that aspect of the story and he has something much more surprising in store since he also wrote the script for this one.

While the mental divisions of those with dissociative identity disorder have long fascinated and eluded science, it is believed that some can also manifest unique physical attributes for each personality, a cognitive and physiological prism within a single being.

Though Kevin (James McAvoy) has evidenced 23 personalities to his trusted psychiatrist, Dr. Fletcher (Betty Buckley), there remains one still submerged who is set to materialize and dominate all the others. Compelled to abduct three teenage girls led by the willful, observant Casey (Anya Taylor-Joy, The Witch), Kevin reaches a war for survival among all of those contained within him—as well as everyone around him—as the walls between his compartments shatter apart.
